INVLNTOR. [.eo' Bissau BY L. J. BISSON INTERLOCKING GAME BOARD Filed March 31 1948 Feb. 14, 1950 Fig 1 Patented Feb. 14, 1950 UNITED STATES PATENT OFFICE I mraanoci r ti ma BOARD Leo J. Bissor. Somersworth, N. 1!. Application March 31, 1948, Serial No. 18.086 1 Claim. (Cl. 273-130) The present invention relates to improvements in playing cards and, more specifically, to a new and improved set of interlocking playing cards.

{when playing a game of beano or bingo or thelike, each player, can have anywhere from one card to any number that he "pays" to play. when a player has-let us say-five, ten or some time even as many as fifteen cards to play he has difficulty in gathering the beans or whatever the players use to mark off the numbers with, because the loose cards move and the beans or other markers fall in between every card. With cards which have been used hitherto it is often practically impossible to hold all cards of a player in place and to prevent the beans or the like from sliding in between the cards, which is highly objectionable because it makes the collecting of the beans or the markers very bothersome and interlocked as well as disconnected from one an other easily, within a minute period of time, and without the application of any considerable amount of skill.

A further object of the present invention is the provision of a set of playing cards which can be interlocked with one another and whose interlocking means are so constructed that they will not tear or break off during normal, frequent usage, and which are so simple that they do not cause any appreciable increase in the cost of manufacturing these cards.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

In the accompanying drawings the preferred I forms of the invention have been shown.

In said drawings:

Figure 1 is a top plan view of a preferred emv 2 modified card according to the present invention;

Fig. 5 is a side elevation of the card of Fig. 4;

,Fig. 8 is a fractional enlarged plan view of two interlocked cards of the modification of Figs. 4 and .5; and Fig. 'l is a fractional cross-sectional view on the line 1-1 of Fig. 6.

Similar reference characters refer to. similar parts throughout the several views.

The generic characteristic feature of both modifications is that each individual card has marginal cut-outs on two of its angularly adjoining edge portions and laterally protruding tongues on the other edge portions adapted for .interlocking the cut-outs of other cards of the set. Referring first to Figs. 1 to 3, each card i has marginal, inwardly diverging cut-outs 2 and marginal outwardly diverging tongues 3, which fit into the cut-outs 2 of the' adjoining cards I as may be seen in Fig. 3.

As per the modification of Figs. 4 to 7 inclusive, each card 4 has extending'from two edge portions taper tongues 5, while each of the remaining edge portions is provided with a pair of trapezoidal slots 0 and I, and the slotted areas are bulged upwardly for facilitating the engaging of the slots 8 and 1 by the taper tongues 5, as may be seen in Figs. 6 and 7. I prefer also to bend the tongue portion I, so that an absolutely even surface will be attained when the cards are interlocked. The taper shape of the tongues 5 will insure a firm frictional engagement with the slots I and I, .so that an undesired disengaging of the cards will be avoided.

Since certain changes may be made in the above article and dliferent embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which as a matter of language might be said to fall therebetween.

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent in the United States is:

In a set of polygonal playing cards a polygonal card having in two of its angularly adjoining edge portions a pair of trapezoidal slots which are parallel to the edges of the card, and the card being provided with tapered tongues extending laterally from the remaining edge portions, the slotted UNITED STATES PATENTS Name Date Jaeaer Aug. 2'1. 190'!
